Once again I have released a new version of my MS-DOS based graphical shell, Costa.

The main feature in this new version is support for multiple profiles. It is now possible for several users to use the same installation of Costa, each with their own settings, theme and personal desktop. One user could also have separate profiles for work, play etc.

Over the past couple of years I have been using Open Source software increasingly. More and more of the applications I use everyday have been replaced by open source alternatives, and I now only have a handful of proprietary software left. Even my operating system has been replaced by Ubuntu Gnome.

Since I am using so much open source software, I figured I would live up to this ideal by releasing the source code to one of my own pieces of software, The Costa GUI.

A hobby coding project of mine, Costa is a program which runs on top of MS-DOS or compatible operating systems. The aim of it is to replace the DOS-prompt with a clean, user-friendly interface – a so called GUI (Graphical User Interface). Costa comes with full mouse and keyboard support, and a bunch of useful accessories.

Most development took place between 2004 and 2012, when version 1.0 was released. Since then I have moved on to other projects, and now rarely fire up the code editor to work on Costa.
